Centrality dependence of J/ψ and ψ(2S) production and nuclear modification in p-Pb collisions at √sNN = 8.16 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

The inclusive production of the J/ψ and ψ(2S) charmonium states is studied as a function of centrality in p-Pb collisions at a centre-of-mass energy per nucleon pair √sNN = 8.16 TeV at the LHC. The measurement is performed in the dimuon decay channel with the ALICE apparatus in the centre-of-mass rapidity intervals −4.46 < ycms < −2.96 (Pb-going direction) and 2.03 < ycms < 3.53 (p-going direction), down to zero transverse momentum (pT). The J/ψ and ψ(2S) production cross sections are evaluated as a func- tion of the collision centrality, estimated through the energy deposited in the zero degr ...Daha fazlası

First measurement of quarkonium polarization in nuclear collisions at the LHC

KARASU UYSAL, Ayben | ALICE Collaboration

The polarization of inclusive J/ψ and Υ(1S) produced in Pb–Pb collisions at √sNN = 5.02 TeV at the LHC is measured with the ALICE detector. The study is carried out by reconstructing the quarkonium through its decay to muon pairs in the rapidity region 2.5 < y < 4 and measuring the polar and azimuthal angular distributions of the muons. The polarization parameters λθ, λφ and λθφ are measured in the helicity and Collins-Soper reference frames, in the transverse momentum interval 2 < pT < 10 GeV/c and pT < 15 GeV/c for the J/ψ and Υ(1S), respectively. The polarization parameters for the J/ψ are ...Daha fazlası

Measurement of the production cross section of prompt Ksi-0c baryons at midrapidity in pp collisions at √s = 5.02 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

The transverse momentum (pT) differential cross section of the charm-strange baryon Ξ0c is measured at midrapidity (|y|< 0.5) via its semileptonic decay into e+Ξ−νe in pp collisions at s√ = 5.02 TeV with the ALICE detector at the LHC. The ratio of the pT-differential Ξ0c-baryon and D0-meson production cross sections is also reported. The measurements are compared with simulations with different tunes of the PYTHIA 8 event generator, with predictions from a statistical hadronisation model (SHM) with a largely augmented set of charm-baryon states beyond the current lists of the Particle Data Gro ...Daha fazlası

Λ c+ production in p p and in p -Pb collisions at sNN = 5.02 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

The production cross section of prompt Λc+ charm baryons was measured with the ALICE detector at the LHC at midrapidity in proton-proton (pp) and proton-lead (p–Pb) collisions at a center-of-mass energy per nucleon pair of sNN=5.02TeV. The Λc+ and Λ¯c− baryons were reconstructed in the hadronic decay channels Λc+→pK−π+ and Λc+→pKS0 and respective charge conjugates. The measured differential cross sections as a function of transverse momentum (pT) and the pT-integrated Λc+ production cross section in pp and in p–Pb collisions are presented. The Λc+ nuclear modification factor (RpPb), calculated ...Daha fazlası

Elliptic Flow of Electrons from Beauty-Hadron Decays in Pb-Pb Collisions at sNN=5.02TeV

KARASU UYSAL, Ayben | ALICE Collaboration

The elliptic flow of electrons from beauty hadron decays at midrapidity (jyj < 0.8) is measured in Pb-Pb collisions at sNN 1⁄4 5.02 TeV with the ALICE detector at the LHC. The azimuthal distribution of the particles produced in the collisions can be parametrized with a Fourier expansion, in which the second harmonic coefficient represents the elliptic flow, v2. The v2 coefficient of electrons from beauty hadron decays is measured for the first time in the transverse momentum (pT ) range 1.3–6 GeV=c in the centrality class 30%–50%. The measurement of electrons from beauty-hadron decays exploits ...Daha fazlası

Kaon–proton strong interaction at low relative momentum via femtoscopy in Pb–Pb collisions at the LHC

KARASU UYSAL, Ayben | ALICE Collaboration

In quantum scattering processes between two particles, aspects characterizing the strong and Coulomb forces can be observed in kinematic distributions of the particle pairs. The sensitivity to the interaction potential reaches a maximum at low relative momentum and vanishing distance between the two particles. Ultrarelativistic heavy-ion collisions at the LHC provide an abundant source of many hadron species and can be employed as a measurement method of scattering parameters that is complementary to scattering experiments. This study confirms that momentum correlations of particles produced i ...Daha fazlası
